spasmolytic, antioxidant, anti-inflammatory and immuno-modulatory properties of ginger (rhizome of zingiber officinale roscoe) suggest that it may has beneficial effects on inflammatory bowel diseases. in the present study, the effect of this herbal extract on a model of acute colitis was evaluated. ginger hydroalcoholic extract with doses of 150, 350, 700 mg/kg, prednisolone (2 mg/kg), or vehi...

L ouis Pasteur and Robert Koch are considered the founders of medical bacteriology. Their paths crossed only a few times but, as often happens for such geniuses, those encounters evinced polemics and controversy. Was this due to their different backgrounds? Robert Koch was a physician, 20 years younger than Pasteur, a chemist and microbiologist. Neither man understood the other’s language. Yet ...

We introduce an informative labeling algorithm for the vertices of a family of Koch networks. Each of the labels is consisted of two parts, the precise position and the time adding to Koch networks. The shortest path routing between any two vertices is determined only on the basis of their labels, and the routing is calculated only by few computations. The rigorous solutions of betweenness cent...

We study a generalization of the von Koch Curve, which has two parameters, an integer n and a real number c on the interval (0, 1). This von Koch type curve is constructed as the limit of a recursive process that starts with a regular n-gon (or line segment) and repeatedly replaces the middle c portion of an interval by the n− 1 other sides of a regular n-gon placed contiguous to the interval. ...

The main British population of Gortyna borelii occurs on the north Essex coast, on sites very close to sea level. During 1999, 2000 and 2001, ovipositing strategies of G. borelii were studied providing details of egg laying behaviour, preferred oviposition host plants, height of ova deposition and distance of the oviposition site from the nearest larval food plant (Peucedanum officinale). Six o...

The effectiveness of aqueous extract of seven locally available medicinal plants i.e. Trachyspermum ammi (seeds), Zingiber officinale (rhizome), Tinospora cordifolia (leaves), Cymbopogon citratus (leaves), Moringa oleifera (bark) were evaluated against the plant pathogenic fungus i.e. Fusarium oxysporum f. sp. lini (causing wilt in linseed). The plant extracts were screened for their antagonist...

This paper presents two methods for generating Koch curves, analogous to the commonly used iterative methods for producing images of Julia sets. The attractive method is based on a characterization of Koch curves as the smallest nonempty sets closed with respect to a union of similarities on the plane. This characterization was first studied by Hutchinson. The repelling method is in principle d...

A formula for the interior ε-neighbourhood of the classical von Koch snowflake curve is computed in detail. This function of ε is shown to match quite closely with earlier predictions from [La-vF1] of what it should be, but is also much more precise. The resulting ‘tube formula’ is expressed in terms of the Fourier coefficients of a suitable nonlinear and periodic analogue of the standard Canto...

Dendrobium Officinale is the rare Chinese herbal medicine. This paper will introduce its low cost grade determining system research mainly from the following two aspects: First of all, choose low cost CCD to do image capture, apply machine vision algorithm to extract the stem edge image, and automatically determine the stem diameter size and determine the uniformity coefficient of its size; Sec...
